I liked how you switched to the apostrophe in the middle, speaking to the meteor instead of just describing its descent like you did in the beginning. Sometimes things like that can be confusing, but it worked here.

Wow, really cool poem! I loved that idea; and you're so right-things from space really open up our perspectives as to the insignificance and un-aloness of Earth. That could be emphasized by using "tiny" as an adjective for Earth intead of "quiet," perhaps.

I think the last line is the most awkward in the poem, and I've been thinking of how to word it better but so far I haven't had any luck. My favorite lines were "Its greatest triumph, coming here/ From origins divine." and "the passionate kiss you gave to Earth"-those are really pretty lines. :-)
